New mojo 80 has pretty much the same flex pattern with the mad_trix. Stiffer tail, softer tip. No more "choose your tip and tail" sticker. Yes, they are supposed to be center mounted (i mean that mounting spot is at true center now). A bit wider - in 181 they are 113-80-107. And Jon's signature that makes them soo much better, you know. lol

Not sure that everyone can read this but there's nothing interesting.
And there were lots of pics with them here.
